ISO 10121-1:2014 aims to provide an objective laboratory test method, a suggested apparatus, normative test sections and normative tests for evaluation of three different solid gas-phase air cleaning media (GPACM) or GPACM configurations for use in gas-phase air cleaning devices intended for general filtration applications. ISO 10121-1:2014 is specifically intended for challenge testing and not for general material evaluation or pore system characterization. The three different types of GPACM identified in ISO 10121-1:2014 are GPACM-LF (particles of different shape and size intended for e.g. Loose Fill applications), GPACM-FL (FLat sheet fabric intended for e.g. flat one layer, pleated or bag type devices) and GPACM-TS (three dimensional structures that are many times thicker than flat sheet and e.g. used as finished elements in a device). The tests are conducted in an air stream and the GPACM configurations are challenged with test gases under steady-state conditions. Since elevated gas challenge concentrations (relative to general ventilation applications) are used, test data should be used to compare GPACM within the same configuration and not for the purpose of predicting performance in a real situation. It is also not implied that different GPACM configurations can be directly compared. The primary intention is to be able to compare like GPACM configurations to like, not between GPACM configurations. Testing of complete devices is described in ISO 10121‑2. To ensure objectivity for test equipment suppliers, no specific design of the test apparatus is defined: an example is illustrated in an annex. Instead normative demands for media sample holder design, apparatus properties and validation tests are specified.
Abstract
Overview
ISO 10121-1:2014 specifies a laboratory test method for assessing the performance of gas‑phase air cleaning media (GPACM) used in general ventilation. It provides an objective, challenge‑test approach (steady‑state gas stream) and normative requirements for sample holders, apparatus properties and validation tests. The standard covers three GPACM configurations-GPACM‑LF (Loose Fill), GPACM‑FL (Flat sheet) and GPACM‑TS (Three‑dimensional structures)-and is intended to allow like‑for‑like comparison of media performance in a controlled laboratory setting. Testing of complete devices is covered by ISO 10121‑2.
Key topics and technical requirements
- Scope and purpose: Comparative challenge testing of GPACM for general ventilation; not intended for pore‑system characterization or direct prediction of field performance.
- Media configurations: Definitions and test approaches for GPACM‑LF (particles), GPACM‑FL (flat fabrics/sheets) and GPACM‑TS (thicker 3‑D elements).
- Challenge testing: Tests use elevated challenge gas concentrations under steady‑state airflow; results are for internal comparison, not for direct real‑world extrapolation.
- Apparatus requirements & validation: Normative demands on sample holder geometry, apparatus performance and validation tests (Annex A); no single prescriptive test rig - an example design is provided (Annex C).
- Test sequence and sampling: Structured test sequence, sampling procedures and test parameters for each GPACM type (Annex D).
- Challenge gases & analysis: Guidance on suitable test gases, generation and analysis techniques (informative Annex B).
- Key metrics & terminology: Breakthrough, penetration, capacity, efficiency vs. time and efficiency vs. capacity curves, face velocity and bypass are defined and used for evaluation.
Practical applications and users
ISO 10121‑1 is practical for:
- Media manufacturers seeking benchmark data for product development and quality control.
- Air‑cleaning device manufacturers needing standardized media performance data to design GPACDs.
- Independent test laboratories implementing validated challenge tests for product comparison.
- HVAC engineers, specifiers and building owners who require standardized performance data when selecting sorptive media for general ventilation applications. Note: because tests use elevated concentrations and laboratory sample sizes, users should interpret results as comparative within the same GPACM configuration.
